I have been using Domotz Pro for almost 2 years now and my main purpose was to get a good program that could spot new devices popping up in the network to spot strange behavior BUT also to keep track of the status of all my existing "good" devices and see if important ones goes offline. I have tried to find other similar products on the market but have not found one that is as good as Domotz.
Very quickly spots new devices in the network and also keeps track of what port in the switch it comes through. And also keeps a good view of all the devices and tracks status. Also the software is developed and new smart features and is added on a regular basis.
So far there is really no things that I dislike. It really works OK in my opinion. The only thing that I do not like is that they have removed the "Lite" version so private persons like myself could afford to use this powerful software. (I have been running the "Legacy Lite plan" at an affordable level for a private user but you could not order that any more) However, apart from that and for businesses I still would recommend this as it is a good software for sure.
